SANYO DENKI Develops Ø175 × 69 mm Splash Proof Centrifugal Fan
Industry's Highest Airflow and Static Pressure

August 8, 2018

SANYO DENKI CO., LTD. has developed and released the San Ace 175W 9W2T type Ø175 × 69 mm Splash Proof Centrifugal Fan.
Among equally sized centrifugal fans with IP56 water protection, this fan features the highest airflow and static pressure in the industry.(1)
It is suitable for outdoor ICT equipment, PV inverters, commercial refrigerators, air conditioning equipment, and dust collectors.
It also comes equipped with the PWM control function to externally control the fan speed.

San Ace 170W


1. High Airflow and High Static Pressure

This fan delivers a maximum airflow of 17.3 m3/min and a maximum static pressure of 1,100 Pa. Compared with the current model(2), the maximum airflow and maximum static pressure have increased to approximately 1.9 times and 3 times, respectively.

2. Water and Dust Resistance

Its IP56-rated(3) water and dust protection ensures stable fan operation even in harsh environments.

3. High Energy Efficiency and Low Noise

The PWM control function enables the external control of fan speed, contributing to lowering noise and improving energy efficiency of devices.

(1) Based on our own research as of August 8, 2018, among equally-sized industrial waterproof centrifugal fans on the market.

(2) Current model: San Ace 175W 9W1T type Ø175 × 69 mm Splash Proof Centrifugal Fan (model no.: 9W1TG48P0H61).

The degree of protection (IP code) is defined by IEC 60529 (International Electrotechnical Commission).
・Protection against a level of dust that could hinder operation or impair safety
・Protection against powerful water jets
